LOOSE-LEAF BINDER.

' Speciflcationoi Letters Patent.

Patented Oct. 27, 1908.

Application filed August 9, 1906. Serial No. 829,830.

To all/whom it may concern: I

Be it known that 1, WILLIA M. WHEIL- dent of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Im rovements in Loose-Leaf Binders, of whic the following is a specification.

My invention relates to the construction of loose leaf binders for loose leafledgers, memorandumv books and the like and it consists in sundry improvements herein described.

In the drawings .hereto annexed, Figure 1 .is a perspective view of my new loose leaf binder in its closed or leaf retaining position.

- Fig. 2 is a similar view of my loose leaf binder in its open or leaf-receiving position.

Fig. 3 shows a modification. Fig. 4 shows another modification. Fig. 5 shows a retaining means which may be used to hold my loose loaf binder in its closed position.

' secured by suitable rivets or otherwise to the.

The preferred form of binder is illustrated 'in Figs. 1 and 2 and the preferred retaining means is shown in Fig. 5. Inthe preferred form the device consists of two fiat bars, A

and A, usually made of metal, pivoted to ether at B near their middleportions, each bar carrying an upwardly extending leaf receiving member a onopposite ends and opposite sides. The loose leaves are suita ly perforated 01 punched to receive the ends of the leaf receiving members, preferably a member on one end of the bar and a member on the opposite end of the other bar. The unched or slotted leaves are adjusted over he'se members while the device is in the open position shown in Fig. 2, and the device is then closed, the respective opposed leaf receiving mehibers a upon the bars coming together to form a complete ring or loose leaf retaining inember from which the leaves cannot csca e. When so closed and the leaves thus'tlireaded upon the two rin s thus formed, the device is inserted in the c annel C of metal or other suitable material shown in Fig. 5, and the two bars thus locked in their operative leaf-retainingposition. The channel C shown in Fig. 5 is designed to be cover of the account book or memorandum book.

Any desired number of leaves or sheets .within the capacity of the leaf-retaining rings may be threaded in the manner'described, and any sheet may be withdrawn or inserted at will without disturbing the arwhich, as shown in Fig. 1, are upon opposite sides and "opposite ends of. each plate, are differently arran ed' and the pivot point B is also at one on of the two bars, instead of central of the two bars as shown in Figs. 1 and 2. The mode of operation is similar to the mode of operation of the device shown in Figs. 1 and 2.

" In the modification shown. in Fig. 4 the two bars A, A are substantially identical organization and structure with the bars shown in Figs. 1 and 2, and they are pivoted at their middle portions at B as is the device of Figs. '1 and 2, but a retaining means diifer- 'ent from that employed in Figs. 1 and 2 is shown, viz. a spring finger D upon the end of one bar and a corresponding recess E in the end of the other bar, organizedand arranged to interlock when the two bars are brought into their closed orleaf-retaining position.

It is obvious that the locking means to hold the parts of my loose leaf binder in operposition may be either the ative or closed means shown in ig. 4 or the means shown in Fig. 5, and many other suitable locking means to hold the two parts together in closed position may be used.

I further design to utilize the central pivot shown in Fig. 4 to connect the binder with the cover of the book in which it is employed.

I claim:

1. A loose-leaf binder, consisting of two bars each having a leaf-receiving half member secured thereto in opposed and cooperating relation to a half member upon the other bar, the said bars being movably secured together by a pivot in; means to retain the two bars in their eaf retaining position, all organized and arranged substantially as shown and described.

2. A loose-leaf binder, consisting of two bars each having a lcaf holding half member secured thereto u on opposite sides and ends, the said bars eing pivotally connected at their middle portions, and a channel, properly shaped and proportioned to receive the two bars in their leaf retaining position, all organized and arrangedsubstantially as shown and described.

3. A device of the character described comprising two members each supplied with a plurality of leaf holders, pivoted together by a pivot parallel to the plane of said leaf holders at a point lying between the outermost leaf holders supported by each member and adapted to permit one of said members to rotate about said pivot through a limited are, and means for locking said members together when closed.

4. A device of the character described, comprising two members, each provided with a plurality of leaf holders and ivoted together by a pivot parallel to the p ane of said leaf holders at a point intermediate the outermost leaf holders, a protuberance on one of said members, and an opening in the other member ada ted to cooperate with said rotuberance to ock the members togetherw en in closed position.

' 5. A device of the character described, comprising two superimposed members pivoted together by a ivot extending trans versely through bot members and each providedwitha plurality of curved members adapted to coact in pairs to form suitable leaf holders; and "means for locking said' members together.

I 6. A device of the character described comprising two flat members pivoted together by a pivot at right angles to saidfiattened sides at a point substantially midway of the length of one thereof and adapted to gether when said leaf hol er's are in cooper- I ating position.
